Resistance of Stretched Wires
JEE Main asked Resistance of Stretched Wires 8 times in 8 of the 108 shifts Lumi analysed, in 2021, 2022, 2023 and 2024. It belongs to Ohm's Law and Resistance, in Current Electricity (Physics). The longest wait between two years asking it was 1 year. In 2021, 2022 and 2024 it came in more than one shift of the same year.

Questions on this idea a shift, by year
2017–2026. Asked in 2021, 2022, 2023 and 2024. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift of 25 Physics questions.
Raw count: 2017: 0 in 1 shift · 2020: 0 in 12 shifts · 2021: 2 in 24 shifts · 2022: 3 in 24 shifts · 2023: 1 in 12 shifts · 2024: 2 in 18 shifts · 2025: 0 in 8 shifts · 2026: 0 in 9 shifts.
